10 Functional Mushrooms and What Traditional Wellness Practices Used Them For

Published June 2026 · Pilly Labs Editorial

Long before anyone called them "functional mushrooms" or put them in supplement capsules, these organisms were woven into the daily rhythms of cultures across the world. Chinese emperors consumed Reishi. Siberian villagers brewed Chaga into dark, bitter tea through six months of winter. Japanese monks cultivated Shiitake on fallen oak logs. Tibetan herders collected Cordyceps by hand at 15,000 feet.

What makes this history remarkable is not that one culture discovered mushrooms were useful. It is that dozens of cultures, separated by oceans and centuries, arrived at overlapping conclusions independently. Chinese, Japanese, Korean, Siberian, Finnish, Brazilian, and Southeast Asian traditions all developed distinct mushroom practices without any shared knowledge base. That convergence is not proof of efficacy in the modern clinical sense, but it is a striking pattern — and the reason researchers are now studying these organisms with increasing seriousness.

Here are the 10 mushrooms in the Pilly Labs 10-Blend, and the traditions behind each one.

1. Lion's Mane — Hericium erinaceus

Traditional origin: Chinese and Japanese medicine

Buddhist monks reportedly drank Lion's Mane tea before meditation to sharpen focus and clarity. In Traditional Chinese Medicine (TCM), it was valued for supporting digestive and cognitive wellness. The Japanese name yamabushitake references the Yamabushi mountain ascetic monks who used it.

Lion's Mane is notable because its traditional reputation has found some modern support. A 2009 double-blind trial by Mori et al. found that supplementation supported cognitive function scores in older adults during the study period.¹ Researchers have identified compounds called hericenones and erinacines that may support nerve growth factor production, though this research remains in early stages. Among the 10 mushrooms here, Lion's Mane has one of the strongest bridges between traditional use and human evidence.

2. Cordyceps — Cordyceps militaris

Traditional origin: Tibetan and Chinese medicine

Wild Cordyceps sinensis has one of the most extraordinary origin stories in natural history. It is a parasitic fungus that colonizes caterpillar larvae high on the Tibetan Plateau — above 3,500 meters — where yak herders first noticed their animals becoming more vigorous after grazing in Cordyceps-rich pastures. For centuries, it was one of the most expensive ingredients in TCM, traditionally used to support energy, stamina, and respiratory vitality. At times, its value rivaled gold by weight.

Modern supplements use cultivated Cordyceps militaris, which can be grown without insect hosts. Preliminary human research has explored its potential to support exercise performance and oxygen utilization, though larger trials are needed.²

3. Reishi — Ganoderma lucidum

Traditional origin: Chinese, Japanese, and Korean medicine

No mushroom carries more cultural weight than Reishi. Known as lingzhi in Chinese — literally "spirit plant" or "divine mushroom" — it has appeared in Chinese medical texts, imperial art, and palace architecture for over 2,000 years. Reishi was so revered that carved Reishi motifs decorated the Forbidden City, and it was traditionally reserved for royalty and the wealthy.

Traditional practitioners used Reishi as a tonic for vitality, longevity, and balance — particularly during periods of occasional stress. In Japanese tradition, it is called mannentake, the "10,000-year mushroom." Modern research has identified triterpenoids and polysaccharides as its key bioactive compounds, though human clinical evidence remains limited relative to the depth of its traditional pedigree.

4. Chaga — Inonotus obliquus

Traditional origin: Siberian, Russian, and Northern European folk medicine

Chaga does not look like a mushroom. It forms as a dark, cracked, charcoal-like mass on birch trees in the coldest climates on Earth — Siberia, northern Russia, Finland, northern Canada. For centuries, Siberian and Russian communities harvested it from birch trunks, dried it, and brewed it into a dark, bitter tea consumed daily through long winters as a general vitality tonic.

Chaga's bioactive profile is distinctive: high in polysaccharides, betulinic acid derivatives (absorbed from its birch host), and melanin pigments. Laboratory analyses have measured exceptionally high ORAC values, though the practical significance of ORAC scores for human health is debated. Its traditional use is deep and well-documented across multiple northern cultures; its clinical evidence in humans is still developing.

5. Shiitake — Lentinula edodes

Traditional origin: Chinese and Japanese cuisine and medicine

Shiitake is the most familiar mushroom on this list — the one most likely already in your kitchen. Cultivated on hardwood logs in China and Japan for over 1,000 years, Shiitake occupied a dual role as both a prized culinary ingredient and a traditional wellness staple, valued for supporting everyday immune wellness and overall vitality.

Among functional mushrooms, Shiitake has one of the stronger human evidence bases. A 2015 study by Dai et al. found that daily Shiitake consumption was associated with favorable changes in immune cell markers in healthy adults over four weeks.³ The compound lentinan, a beta-glucan in Shiitake, has been extensively researched in laboratory settings. This combination of culinary tradition, centuries of wellness use, and emerging human data gives Shiitake a uniquely well-rounded profile.

6. Maitake — Grifola frondosa

Traditional origin: Japanese medicine

Maitake translates to "dancing mushroom" in Japanese. Legend holds that foragers danced with joy upon finding it wild at the base of oak trees in northeastern Japan — it was that valuable. Maitake was traditionally used to support immune wellness and general vitality, and it was prized as a culinary delicacy with an earthy, complex flavor.

Maitake contains a unique beta-glucan fraction called D-fraction (MD-fraction) that has attracted laboratory research interest. However, human clinical data remains limited. Its role in modern supplements draws primarily from its extensive traditional use in Japanese wellness practices and its distinctive bioactive profile.

7. Turkey Tail — Trametes versicolor

Traditional origin: Chinese and Japanese medicine

Turkey Tail is among the most common mushrooms on Earth, found growing on dead hardwood across every inhabited continent. Its concentric bands of brown, tan, and cream resemble a wild turkey's fanned tail feathers — hence the name. In Chinese medicine, it is known as yun zhi ("cloud mushroom"); in Japanese tradition, kawaratake.

Turkey Tail has been traditionally used for centuries as a tea for general wellness and vitality support. It contains polysaccharide-K (PSK) and polysaccharopeptide (PSP), which have been subjects of substantial laboratory research. Turkey Tail's traditional use is extensive across Asian cultures, and its bioactive compound profile has attracted significant scientific interest, though consumer supplement forms are distinct from pharmaceutical preparations.

8. White Button Mushroom — Agaricus bisporus

Traditional origin: European cultivation (17th century onward)

White Button mushrooms lack the exotic mystique of Reishi or the dramatic origin story of Cordyceps, but they are the most consumed mushroom species on the planet. First cultivated in France around 1650, they became a global staple and the default "mushroom" in Western cuisine.

Their inclusion in functional blends is not arbitrary. White Button mushrooms are a natural source of ergothioneine (an amino acid with antioxidant properties), selenium, B vitamins, and beta-glucans. They also produce vitamin D2 when exposed to UV light — one of the very few non-animal food sources of vitamin D. Their bioactive profile, combined with their deep history as a nutritive food, gives them a meaningful role in a broad-spectrum blend.

9. Black Fungus — Auricularia auricula-judae

Traditional origin: Chinese and Southeast Asian cuisine and medicine

Black Fungus — also called wood ear or cloud ear — has been a staple of Chinese cooking and TCM for over 1,500 years. Its distinctive gelatinous, ear-shaped fruiting body grows on decaying wood, and it has been traditionally used to support cardiovascular wellness and blood vitality in Chinese medical practice.

Rich in polysaccharides, dietary fiber, and notable levels of iron, Black Fungus is one of the most widely consumed mushrooms in Asian cuisine. Its inclusion in functional blends honors its deep roots in Chinese and Southeast Asian wellness traditions and adds a unique polysaccharide profile to the overall spectrum of compounds.

10. Royal Sun Agaricus — Agaricus blazei

Traditional origin: Brazilian folk medicine; later adopted in Japanese wellness

Royal Sun Agaricus has one of the most unusual cross-cultural journeys in the mushroom world. Native to the Piedade region of Brazil, it was traditionally used by local communities as a general wellness tonic under the name cogumelo do sol ("mushroom of the sun"). In the 1960s, Japanese researchers studying the region's reportedly favorable health patterns brought the mushroom to Japan, where it became known as himematsutake and grew into one of the country's most popular functional mushrooms.

Royal Sun Agaricus contains polysaccharides, including beta-glucans, and has been the subject of laboratory research in both Brazil and Japan. Its presence in a multi-mushroom blend represents a genuinely global tradition — South American folk use, validated by Asian scientific curiosity, now part of a modern supplement format.

Ten Mushrooms, Centuries of Convergence

Each of these mushrooms carries a distinct story, a distinct bioactive fingerprint, and a distinct cultural lineage. What unites them is that human communities across the world, with no way to share notes, independently concluded that these organisms were worth paying attention to. Modern science has not yet confirmed everything traditional practice suggests. But it has confirmed enough to make the investigation worth pursuing — and enough to justify including these ingredients as part of a daily wellness routine grounded in both tradition and transparency.
